DISPLAY CARTON HAVING A FILM OVERLAP Q Filed Jan. 26. 1966 MMW i UnitedStates Patent US. Cl. 229-37 1 Claim ABSTRACT OF THE DISCLOSURE Apaperboard carton having a strip offiexible decorative material disposedover [the outer surfaces of the carton side walls and being attached atits ends to the carton at a corner of the carton in such a way that thestrip can be readily removed without damaging the outer surfaces of thecanton walls.

This invention relates to a method of aflixing a sheet of plastic filmacross the front surface of a paperboard panel in a manner so that thesheet can readily be separated from the panel, when desired, withoutdamaging or mar ring the front surface.

This invention forms an improvement in and is particularly suited forpromotional display cartons, such as is commonly used for Christmaswrapped whiskey cartons, each having a gayly colored and decorated outerfilm band encircling the carton body. The film band converts aconventionally printed carton to a festive holiday carton; but the filmband can be readily torn from the carton for sale of the product afterthe holiday season. The invention will be described as applied to aconventional tubular car-ton, but it should be noted that this inventionis useful in other applications also.

An object of this invention is to provide improved methods of aflixing afilm sheet relative to a paperboard panel in a manner to extend freelyand unc'onnectively across the front surface of the panel to permitready separation of the sheet, when desired, without marring the frontsurface of the panel.

In the accompanying drawing:

FIG. 1 is a perspective view of a tubular style carton having a filmband secured thereto in a manner taught by the subject invention;

FIGS. 2, 3, 4, 5, 6, and 7 are perspective views, to a reduced scale, ofa blank suitable for forming the canton of FIG. 1 and showing the mannerin which the display band is secured to the carton and the carton isformed, each sequentially numbered figure showing a progressive step inthe formation of the carton.

In FIG. 1, a conventional tubular style carton 10 is shown and includesopposed pairs of side walls 12 and 14, and top wall 16 and a bottom wall(not shown) connected to the opposite ends of the side walls. A band 20is shown to extend across the exterior surfaces of the adjacent sidewalls 14 and 16 and is also understood to traverse the hidden walls toencircle the carton.

The band 20 is free from connection to any of the exterior surfaces ofthese side walls and is connected to the canton only at the corner 22 ofthe carton at the conventional lapped manufacturers joint. The band 20can be printed in a decorative manner to lend a seasonal character tothe carton, but the band can also be separated from the carton 10 merelyby inserting a knife blade or equivalent between the band and the cartonbody and cutting across the band. The loose ends of the band near thefilm confinement at the corner 22 can be trimmed as desired, to leave aconventional canton having unmarred exterior surfaces.

Referring now to the FIGS. 2-7, the manner of secur- 3,445,053 PatentedMay 20, 1969 ing :the film band to the carton is shown. FIGS. 2-7 show,to a reduced scale, a typical carton blank 30 suit-able for forming thecarton 10 shown in FIG. 1. The blank 30 includes consecutively hingedside wall panels 12, 14h, 12h and 14 of the opposed pair of side walls12 and 14, and a lapped glue flap 32 extending from the free end edge ofside wall panel 12. Top and bot-tom closure panels 34, 35, 36, 37, arehinged to the end edges of the side wall panels 12, 14h, 12h, and 14,respectively, and form end closure walls for the tubular carton as iswell-known in the art.

The blank 30 is conventionally formed to a tubular structure by foldingthe side wall panels along the hinge lines 38 and 39 to lap the sidewall panel 14 over the glue flap 32. By applying an adhesive between thelapped glue flap and the side wall panel, a lapped manufacturers jointis formed to hold the blank as a tubular carton structure. The tubularstructure is shipped fiat to the user, where it is opened and loadedwhen desired. After the carton is loaded, the end closure panels 34-37are folded at right angles to the side wall panels and are securedtogether for providing the end closure walls.

According to this invention, the display band 20 is secured to thecarton blank 30 before the latter is folded to and secured as a tubularstructure. In order to show how this is done, the carton blank isillustrated in FIGS. 2-7 in progressive stages of fabrication, thecarton blank progressing from FIGS. 2 and 5 to the right. In the FIGS.2-4, the carton blank is flat with the printed or outside carton sideup. In FIG. 3, a strip of tape 40 is secured to the underside of sidewall panel 14 on its inside or unprinted side in a manner to present anendward portion 42 which projects beyond the end edge of the side wallpanel. The tape can be conventional adhesive tape, transparent orotherwise, so it readily sticks to the panel 14 and further exposes asticky surface at the endward section 42. A line of adhesive 44 is alsoapplied to the top of the glue flap 32 at this point.

In FIG. 4, the display band 20 is placed on the top side of the blank 30to cover part of the exterior printed surfaces of the carton, andfurther to extend over the exposed sticky surfaces of the glued glueflap 32 and the endward portion 42 of the tape 40. The film sheet thusis bonded at its ends to the carton blank 30, and the central section ofthe sheet is free from and not connected to the carton side walls.

After the film sheet is secured to the blank, the blank assembly isflipped over by appropriate means to the position shown in FIGS. 5-7where the printed carton side is faced downwardly and the band 20 islocated on the underside of the blank. In FIG. 5, the underside of glueflap 32 and the top side of the endward portion 42 of the tape 40 arecoated with adhesive strips 46 and 48. The blank progresses along towhere in FIGS. 6 and '7, the side wall panel 12 and glue flap 32, andendward portion 42 of the tape and the band secured thereto are foldedinwardly against the underlying portions of the blank. The end portion42 of the tape thus is adhesively bonded to the inside surface of theside wall panel 14. The side wall panel 14 is then folded fiat againstits underlying panel 12h to overlap and be bonded to the glue flap 32.This defines the tubular carton, as was previously mentioned, andsecures the film band to the blank only at its ends between the lappedmanufacturers joint.

It is possible to eliminate the added step of applying adhesive strip 48to the exposed end portion 42 of the tape 40 by using a tape that isadhesive coated or sticky on both sides. Such tape is commerciallyavailable and would cause the exposed endward portion 42 of the tape tobe adhered to the underlying tape and to the side wall panel 14 merelyby folding the endward portion over.

Commercial equipment can be used for applying the tape to the blank, forlocating the sheet on the blank, and for gluing and folding the blank.Thus, the method of affixing the film sheet can be economicallypracticed on fabricating equipment readily available and at the disposalof most carton manufacturers.

What is claimed is:

1. In a package including a paperboard carton and a readily detachable,decorative outer wrapping thereon, the combination of:

(a) a carton formed from a unitary blank of foldable paperboardincluding:

(i) a plurality of side wall panels hingedly interconnected at theirside edges;

(ii) a relatively narrow glue panel hingedly connected at one side edgeto an adjacent side edge of one of the side wall panels at one end ofsaid blank and having its outer surface adhesively connected to theinner surface of a marginal side portion of another side wall panel atthe other end of said blank in a lap joint which has only twothicknesses of paperboard, to form a tubular structure;

(iii) closure flaps hingedly connected .to end edges inner surface ofsaid marginal side portion of said other side wall panel at said lapjoint;

(d) one of said sheet end portions being adhesively secured to the othersurface of said glue panel and the other end portion extending beyondsaid free marginal side portion of said other side wall panel;

(e) a relative thin strip of flexible material underlying and beingadhesively secured to said other end portion of said sheet and the innersurface of saidmarginal side portion of said other'side wall panel andbeing reverse folded approximately 180 degrees upon itself toaccommodate the interposition of said other end portion of said sheetbetween said other side wall panel and said glue panel at said lapjoint, so that the sheet of decorative material can be removed from saidcarton without marring the outer surface of said carton.-
